POLYCHROME-RIBBON ATTACHMENT FOR TYPE- WRITERS.

- Specification of Letters Patent.

Application filed June 29. 1906. Serial No. 824,051.

To tll whom it may concern:

Be it known that I, JOHN ANDERSON RUF- F1N,$t citizen of the United States, residing at New York city, New York, have invented certain new and useful- Improvements in Polychrome-Ribbon Attachments for Type- Writers, of which the following is a spcilication. 7

My invention is a polychrome-ribbon attachmentfor type-writers, andl have shown it as applied to a machine of the well-known Hammond type. a

The object ofmy invention is to provide a simple construction which will necessitate the employment of no additional parts to the machine over those now used.

In carrying out my invention I provide a y type or ribbon shield of special construction havin a plurality of openings for the passage or" the ammer, the said shield, together with the ribbon-guide, being adjustedvertic'ally in order to brin into play the difierent sections of the ribbon caring the different colors.

Theinvention consists in the features and combination and arrangement of parts here;- in'after. described, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of the invention as embodied in .a' Hammond type-writer. Fig. 2 is a crosssectional view of Fig. l substantiallyon the line 2 2, some of the parts being omitted. Fig. 3 is a view on the line 3 3ofF1g. '1, some of the parts being omitted; and Fig. 4 is a de- I tail view looking frOmtheright of theline 4 4,Fig. 1.

The anvil'l, the shuttle 2, and ribbon spools 3 are of ordinary arrangement, as is a o the hammer 1*. The ribbon passes from the-spool between the shuttlejandthe hammer by way of guidefingers 4 5, ar-l ranged pairs on arms 6, which are pivoted to'a suitable frame part at 7. The type'or' ribbon'shield 8 is carried in the usual manner by arms 9 of curved form to embrace the anvii, the said arms being united at the frontand pivoted to a bracket 10 on the ring or frame l1,-siirrounding the anvil.

As shown in Figs. 2 and 3, the shield is provided with two openings 12, vertically in line with each other and separated by the intact portion 13 of said shield. The polychrome ribbon is indicated in Figs. 2 and 3 at 14, the upper part being of any suitable color for ordinary printing, such as black ,or purple,

While the lower portion is of a difi'erent color,

such as red. These different color-sections and to bring the lower opening 12 oi the type or ribbon shield into such position that the hammer will operate therethrough. In order to effect this vertical adjustment of the type or ribbon shield and the ribbon-guide, I provide a finger-piece 15, connected with the arms '9 and formed by bending up at an inclination the rod or wire of which the said arms are formed. This finger-piece is located in front of the anvil within convenient reach of the operator, and by pressing there- I upon the ribbon-shield arms are elevated to raise the ribbon-shield, so' as to bring the lower section of the ribbon into play. The upward movement of the rib hon-shield. irame also raises the ribbon-guide frame or frames, for which purpose the arms 6 are provided with lugs or fingers 15, extending up- T wardly therefrom and reaching over the arms In order to hold the ribbon shield and guide in their elevatedposition while using the lower 9' of the type or ribbon shield frame.

sectionof the ribbon, I provide a catch 16 at theright of the anvil and having a rest at 17 for supporting the. arm 9. The catch is carriedfby a post or arm'18, extending upwardly from -a plate 19', which carries the alining- IguideZ'O, the saidplate being pivoted to the l'rame at 21, so as to be swung to one side, the

amount of movement being determined by a screw-22, passing through a slot 23. The upper end of the post 18 is formed into a finger button or-knob 24, and by pressing this toward-the right the catch 16 is removed from over the arm 9, so that this may then be elevated by pressure. upon the finger 15, and

then upon releasing the catch 16 it will fly back under the arm 9 of the ribbon-shield frame, so that the said arm will be supported in the rest 17 of the saidcatch. It is simply v24;, when it will be carried to the left by a spring 25 at the pivot 21.

As before stated, when the type or ribbon shield frame is elevated it also elevat s the ribbon-guides by means of contact or the arms 9 with the lugs or fingers 15.

In order to restore the parts to normal position for printing in the ordinary color, it is simply necessary to press the catch 16 toward the right by pressing upon the finger piece or button 24,'s o that the said catch will be removed from under the arm 9, where- 'upon' the ribbon-shield, together with the guides, will drop down to their former position:

' I have so constructed and arranged the parts that the type or ribbon shield may be elevated independently of the other parts, for which purpose it is simply necessary to press the arms 9 toward the left of Fig. 1 from under the lugs or fingers 15, and then the type or ribbon shield frame may be swung upwardly, and it may be held in its raised position by simply pressing it toward thev right, whereupon the pivot portion 26 will slide in the slotted bearing 27 and will'be retained by contact of the portion 28 with the wall 29 of said slot,

in order to limit the movement of the type or ribbon shield, together with the ribbon guides, upwardly when changing from one ribbon section to the other, 1 provide'stops consisting of fingers 30 on the ribbon-guide arms 6, which stops abutagainst the-under side of the frame.

It will benoticed from Fig. 2 that the arms 9 of thetype or ribbon shield framehave a certain amount of lost movement be-- fore they strike theoverlying lugs or fingers 1 1-5 of the ribbon-guide arms 6. This allows. the ribbon-shield to have an excess of movement verticallyrin relation to the ribbonguide and permits the openings-12- to be arr ranged, as indicated in the drawings.

In order to allow the operator to see the printing as it is. being done, the ribbon shield, together with the ribbon-guides, are normally ina lowered position, and means are provided whereby the said shield and guide are elevated .to the printing-planewhen the impression is to be made. This means consist of vertically-extending rods 31, the lower endsof which rest uponrollers 32 of the space-frame 33', arranged as is wellknown in the Hammond machine. The i1pper ends of these rods 31 bear upon the under edges'of the arms 6 of the ribbonuides, and one of'these arms carries a lug or nnger 34m bear on the under side of the ribbon-shield arm 9, and the other guide-arm 6, throu h its lug '15, performs a si'milar function to t 1e lug3a in elevatingthe other arm 9 of the ribbon-shield.- ,Eachftime a key is depressed, therefore. the enae'e rrame through the rods understood that the ribbon 31 will elevate the ribbon and the shield to cooperate with the otherprmtingelements for making theimpression, and when the.

key is released the ribbon and the shield will drop, so that the iast letter prin'ted will be clearly visible to the operator.
